Method and apparatus for identifying network device corresponding to internet protocol address, and method and apparatus for allocating internet protocol address

Abstract

Provided are a method and apparatus for identifying a network device corresponding to an Internet protocol address. The method comprises the steps of detecting network devices over a network using a detection message, extracting media access control addresses from Internet protocol addresses of network devices which respond to the detection message, and detecting and displaying names of network devices corresponding to the extracted media access control addresses from a database which stores device identification information specifying names of network devices and media access control addresses corresponding to the respective names.

[0017] According to one aspect of the present invention, there is provided a method of identifying a network device corresponding to an Internet Protocol address, the method comprising the steps of detecting network devices over a network using a detection message, extracting media access control addresses from Internet protocol addresses of network devices which respond to the detection message, and detecting and displaying names of network devices corresponding to the extracted media access control addresses from a database which stores device identification information specifying names of network devices and media access control addresses corresponding to the respective names.

[0018] According to another aspect of the present invention, there is provided an apparatus for identifying a network device corresponding to an Internet protocol address, the apparatus comprising a device detecting unit for transmitting a detection message to network devices connected to a wired or wireless local area network via the wired or wireless local network device, the detection message allowing detection of the network devices; a media access control address extracting unit for extracting media access control addresses from Internet protocol addresses of network devices which respond to the detection message, respectively; a network device name detecting unit for detecting names of network devices corresponding to the extracted media access control addresses from a database storing device identification information which specifies the names of network devices and media access control addresses corresponding to the respective names; and a displaying unit for displaying the detected names of network devices.

[0019] According to yet another aspect of the present invention, there is provided a method of allocating an Internet protocol addre

Problems solved by technology

However, since an IP address of IPv6 is expressed with 128 bits, it is not easy for a user to memorize the IP address allocated to a network applicant that the user desires to use that has been converted from an IP address of IPv4.

Also, when a network device that a network applicant desires to use does
